Challenge tests

?

Specific migration tests

Challenge tests & specific migration using surrogates

Surrogates = molecules representative of migratable substances

STEP 1 : Enriching with surrogates

STEP 2 : Extraction of surrogates (at each step of the process in the case of challenge tests)

STEP 3 : Analysis

• Epoxiconazole : the most used fungicide

o Acceptable Daily Intake (ADI) = 0.008 mg/kg body weight and per day, i.e. 0.56 mg/day

for a human of 70 kg

o Median residue in wheat straw : 2.71 mg/kg of wheat straw (EFSA, 2008)

• Worse case of migration for PHBV/wheat straw fibres trays

o Trays (30g, 140x130x35 mm3, i.e. 3.7 dm

2 _{) in full contact with food}

o 20 wt% of wheat straw fibres

 Maximal quantity of migratable epoxiconazole = 0.026 mg/kg of food

 This would mean that a daily ingestion of more than 21 kg of food in contact with this

kind of packaging… to reach the value of 0.56 mg/day

• Taking into account the decontamination efficiency (≈80%)

 This would mean that a daily ingestion of more than 88 kg of food in contact with this
